Tre Ville, Montagne, Preore and Ragoli in the Giudicarie
Tre Ville was created in 2016 by merging three municipalities in the Giudicarie: Montagne, Preore and Ragoli. The area lies between Tione di Trento and the entrance to the Val Rendena, at the foot of the Brenta Dolomites, and combines valley-floor villages with hamlets on sunny terraces, backed by meadows, woods and mountains.
Tione, a few minutes away, has schools, a hospital and shops; Trento is further off and reached by car. Buyers here are choosing mountains lived in all year round, with cold winters and life organised around the services in the valley. Houses range from rural buildings in stone and timber, often large and in need of renovation, to newer homes on the edges of the villages.
Istat, the national statistics office, counted 1,386 residents in 2023, slightly down (0.7%) on the 1,396 of 2011. The average age is 46.3, close to the provincial 45.4, and over-65s make up 24.9%. Foreign residents account for 3.2%. Declared incomes are above the Trentino average.
For earthquakes, Tre Ville is in seismic zone 3, like 147 of the 166 municipalities in Trentino, with an expected ground acceleration of 0.068 g. In old buildings, the roof and the connections between walls and floors are the first things to have checked.
Trentino uses the tavolare land registry: ownership is recorded in the land book (libro fondiario) and the Revenue Agency (Agenzia delle Entrate) does not publish cadastral maps, which the report states. On the slopes and along the streams, the report checks the official landslide and flood maps for the address.

Overview
Tre Ville is a municipality in the province of Trento, in Trentino-Alto Adige/Südtirol. At the end of 2023 it had 1,386 residents, ranked 84 of 166 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Tre Ville is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (147 of 166) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.068 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
Population
Compared with the 2011 census, the number of residents is nearly unchanged. The estimated average age is 46 years, in line with the province. 25% of residents are over 65 (the regional figure is 22%). Foreign residents make up 3.2% of the population. On average, a household has 2.2 members.

In tax year 2024, taxpayers in Tre Ville declared an average taxable income of 28,055 euros, above the provincial average (25,718 euros). The Italian average is 24,895 euros.
Tre Ville is in climate zone F, with 3,954 heating degree days, with no limits on when heating may be used. The same table puts the town hall at 1,004 metres above sea level.

Public transport

Radon and contaminated sites
Tre Ville is not among the radon priority areas designated by the Provincia autonoma di Trento in 2026. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list no open contaminated sites in Tre Ville; one has been cleaned up or closed.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Tre Ville: the report checks the address against the ISPRA maps.
House prices
The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
Land registry
For Tre Ville the Revenue Agency does not publish cadastral maps: the land registry here uses the tavolare (land book) system. The report cannot give a parcel reference, but it still checks risks, services and transport at the address and states this clearly.
Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 34 inhabited census areas in Tre Ville. Half of the residents live in areas scoring 61 or more.
